Best ResponseYou've already chosen the best response.0yea, using \[ax^{2}+bx+c=0\] and the \[x=b\pm\frac{ \sqrt{b^{2}4ac} }{ 2a }\]

Best ResponseYou've already chosen the best response.2because you can find common denominaters and put it all over one bar or you can leave it the way it is.

Best ResponseYou've already chosen the best response.2OH yeah...i forgot this was all part of an original equation....this one might be too complicated for the quad formula. have you tried grouping method?

Best ResponseYou've already chosen the best response.0and it was \[x=\frac{9\pm7} { 8 }\] I did the quadratic formula on all of these so far, its a quadratic formula page. they're supposed to use the quadratic formula

Best ResponseYou've already chosen the best response.0its these: \[x_{1}=\frac{ 11+\sqrt{61} }{ 6 }\] and \[x_{1}=\frac{ 11\sqrt{61} }{ 6 }\]
